*Heatsinks are ranked according to the 150W thermal
test results column (rise over ambient temp.). Low temperatures with low
noise levels are considered best. For reference heatsinks with
variable-speed fans, only the high speed (12V) fan test result is included
in the comparison sheet; more detailed results reside in each specific
heatsink review.

Intel
processors vary in power output between single and multi-core models, so
FrostyTech tests heatsinks with two thermal loads that represent the upper limit
of each CPU family, 150W and 85W. With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Coolermaster Hyper TX3 heatsink maintains a
temperature of 23.2°C over ambient at full fan speed (56.0dBA noise).
With an 85W heat
load applied, the Coolermaster Hyper TX3 manages to keep temperatures at a good 14.0°C over ambient.

Again though, the situation takes a turn for higher
temperatures when the 92mm fan is operated at 800RPM. Under the 150W test
conditions, the rise over ambient temperature is a satisfactory 39.4°C. The 85W
test is less impacted of course, posting a result of 26.0°C over ambient result
which is entirely acceptable.

The Coolermaster Hyper TX3 is a simple heatsink which
is easy to install on both AMD and Intel 775/1156 processors. In terms of acoustics, the Hyper TX3 is
a moderately audible at full speed and near silent when CPU duty is low.

I think
it's easiest to sum up the Coolermaster Hyper TX3 by saying this; for 85W TDP
and lower processors it's a good thermal solution at any fan speed.
For +125W TDP chips I'd recommend operating at full fan speed, or
picking any one of the other 56 heatsinks that offer cooler
performance, and occassionally lower noise levels.
